5 Written questions

5 Matching questions

  1. what kind of wave is sound
  2. in phase waves
  3. what is used to accurately describe the characteristics of a sound wave
  4. which acoustic variables are used to distinguish between sound waves and other types of waves
  5. destructive interference
  1. a pressure, density, and distance
  2. b the resultant wave is smaller (of lesser amplitude) than either one of its components
  3. c a pair of waves are considered in phase when their peaks (maximum values) and troughs (minimum values) occur at the same time and in the same location
  4. d there are 7 acoustic parameters: period, frequency, amplitude, power, intensity, wavelength, propagation speed----wif papp
  5. e sound is a mechanical longitudinal wave that moves by compression and rarefaction--particles in the medium vibrate back and forth from a fixed position

5 Multiple choice questions

  1. sound must travel through a medium, it cannot travel through a vacuum
  2. when the frequencies of the waves differ, both constructive and destructive interference occur
  3. pascals (Pa)
  4. that wave is a sound wave
  5. particles move in a direction that is perpendicular (at right angles) to the direction that the wave propagates

5 True/False questions

  1. what kind of line does sound travel insound is a mechanical longitudinal wave that moves by compression and rarefaction--particles in the medium vibrate back and forth from a fixed position

          

  2. units of distancecm,mm

          

  3. interferencewhen multiple beams arrive at an identical location at exactly the same time and thereby lose their individual characteristics and combine to form a single wave

          

  4. what is acoustic propagationall waves carry energy

          

  5. what are some different types of wavessound, light, magnetic, and heat
